Multithreaded filling of @Stateless pools to PoolMin at bean startup

A stateless session bean application can contain minimum instances that need to be created when the application is deployed/started. Currently, these instances are created in a sequence (in a for loop). As a result, the time take for the application to startup is proportional to the time it takes to create all its minimum instances. We need a solution by which these minimum instances are created in parallel.
